Episode 30 — Use Labeling Safely: Quality Controls, Annotation Bias, and Poisoning Exposure
This episode focuses on labeling as both a quality risk and a security risk, because SecAI+ expects you to understand how labels shape model behavior and how attackers or process failures can corrupt labels to produce dangerous outcomes. You will learn why label definitions must be precise, how inconsistent annotator guidance creates noise that looks like “model weakness,” and how annotation bias can encode unfairness or blind spots that later become operational risk. We will explore poisoning exposure during labeling, including malicious relabeling of events, subtle changes that shift decision boundaries, and compromised annotation tools or accounts that allow unauthorized edits. You will practice selecting controls such as double labeling with adjudication, spot checks with gold-standard items, access control and audit logging for labeling platforms, and statistical monitoring for sudden distribution shifts that suggest tampering. The episode ties labeling discipline back to exam scenarios where the best answer is often a process control, not a new algorithm, because reliable labels are the foundation of trustworthy models.
